Work around: (Ref KB 871111)
To work around this issue, use the Cluster command-line utility to set the "DNS Registration Must Succeed" private property to "Not Required." To do this, follow these steps:
Start Cluster Administrator.
To do this, click Start, point to Programs, point to Administrative Tools, and then click Cluster Administrator.
Right-click the corresponding Network Name resource, and then click Take offline.
Open a command prompt on one of the cluster nodes, and then type the following command:
cluster res "network name resource" /priv requiredns=0
In Cluster Administrator, right-click the cluster resource, and then click Bring Online.
Monitor for errors in the logs. This activity requires downtime.
